When is the “inline” keyword effective in C?
It has a semantic effect. To simplify, a function marked inline may be defined multiple times in one program — though all definitions must be equivalent to each other — so presence of inline is required for correctness when including the function definition in headers (which is, in turn, makes...
Declare function as non-static and implement as static inline
Figured it out closely enough. The implementation should be defined as "extern inline" instead: // MyHeader.h int myFunc(void); #if DO_INLINE extern inline int myFunc(void) { return 42; } #endif The compiler will inline this function where it sees fit, but still compile it once as a function, to make it...
Why does C++ inline function has call instructions?
c++,assembly,inlining,inline-functions
You did not optimize so the calls are not inlined You produced an object file (not a .exe) so the calls are not resolved. What you see is a dummy call whose address will be filled by the linker If you compile a full executable you will see the...
inline functions link error C++
The way you wrote it, inline applies to the current file scope. When an inline function is in a header, that header is included in a cpp file, and then the function is inlined where it is used in that file's scope, so there is no problem. In this case,...
Header-only and static-inline-only library in C
c,static,inline-functions,header-only
Yes, it is a bad idea -- especially when integrated with larger libraries. The problem of inline functions' complexity generally increases as these libraries are included and visible to more translations and more complex header inclusion graphs -- which is quite common with larger projects. It becomes much more time...
Defining an inline operator in a different file than the declaration
c++,operator-keyword,inline-functions
From the standard §3.2/3: An inline function shall be defined in every translation unit in which it is odr-used. If you don't define the functions in the header where they're declared inline, then how else do you get the definition into all compilation units that use them? Sure, you can...
“inline” keyword vs “inlining” concept
c++,c,language-lawyer,inline-functions
I wasn't sure about your claim: Smaller functions are automatically "inlined" by optimizer irrespective of inline is mentioned or not... It's quite clear that the user doesn't have any control over function "inlining" with the use of keyword inline. I've heard that compilers are free to ignore your inline request,...
How to compile inline C function with literal attributes with GCC?
c,function,gcc,compiled,inline-functions
Yes, in general gcc will optimise away dead code in inline functions when it can evaluate branches at compile-time. I use this construct a lot to allow optimised code to be generated for different use cases - somewhat like template instantiation in C++.
Are nested functions possible in VBA?
vba,parameter-passing,nested-function,inline-functions
VB.Net can do this, but I don't believe VBA can. Two features that might help you simplify this code in other ways are overloaded functions or optional parameters. Here's an example using optional parameters: Function complicatedFunction(x as Double, Optional param1 as Double = L, Optional param2 as Double = U)...
const parameter with inline functions
c,parameter-passing,const,inline-functions
const, used in inline code or not, is unlikely to preclude optimizations, but it may not necessarily allow for more. But if it applies, there's no good reason not to tell the compiler so that it can make the best use of that information that it can. Update: Since even...
((always_inline)) does not work when function is implemented in different file
Put the implementations is the header. If they're not available in the translation unit in which you intend to do the inlining, you'll be out of luck. The linker (well, a traditional linker) can't do anything about that for you.
